X.25 is very useful for non TCP applications, especially in places where the
infrastructure is less-than-modern.
X.25 used as a layer 2 transport (even though it is not technically a L2
protocol, but then neither is ATM) is useful because it has error checking.

There used to be quite substantial usage of X.25 in Brazil, for a lot longer
than usual, for POS transactions. x.28 in fact, that would be PAD to X.25, may
still be the case ? (RENPAC and 3028 come to mind)
The management of some Nortel GSM devices also could be done over X.25,
usually, it would be backhauled over XOT (or in this case, the Nortel
equivalent) to the management station, from the devices (I'm happy to say, I
don't remember if from the BSCs, or BTSs).
Of course, QLLC and running QLLC to LLC (token ring) devices, was the cherry on
top..SNA on top of X.25, converting to token ring SNA..
Somehow, I can't get rid of the nightmares and the waking in the middle of the
night, thinking about LAPB, and Clear codes and etc., LUs and PUs...the
horror...the horror..

doesn't most of SMS (the crap on GSM's) also run on x.25?
i recall some customer of mine talking X.25 to a telco to get their messages to
the phones anyway.
same for one of our banks not so very long ago...

also: yep.
commercial x.25 based packet radio networks, and the wired parts to keep them
together, are still around.
(the non-commercial ones also ofcourse ;)
